Just got the new ATV 3 connected it all up to the HDMI on the TV power on get the logo thinks great all going well logo disappears with a flicker and blank screen appears. Have reset the ATV using the remote and done a restore with the mini usb. I took it back to the shop they pluged it in to a TV and it all works using my HDMI cable. Called apple they said take to shop to get a new one I did that same problem. My other HDMI devices work fine. TV is a Sony Bravia KDL-32W5710. Pulling my hair out on this one any help world be better than the apple support that just seems to run though the help topic in the user manual help section.
